# Friction

In the above figure it is known that when the blocks are released, they slide. Find the time (in seconds) when the small block will fall off the larger block.

Details and Assumptions

Assume the size of block of mass $$m$$ to be very small.

$$m=1 \text{ kg}$$, $$M=4 \text{ kg}$$, $$l=4 \text{ m}$$, $$\theta=\tan^{-1}\left(\dfrac{3}{4}\right)$$, $$\mu=0.4$$
